Just the idea that we, these little collections of atoms and molecules, are part of the world, but a part that can look at the rest of the world and figure it out in a self-referential way, is kind of breathtaking.

We seek an understanding of the laws of nature and of our particular universe in which everything makes sense to us. We do not want to be reduced to accepting the strange features of our universe as brute facts.

We are not significant on the cosmic scale.

All the stuff we've ever seen in the laboratory, all the kinds of particles and matter and energy, that only makes up 5 percent of our universe.

The fact that you can remember yesterday but not tomorrow is because of entropy. The fact that you're always born young and then you grow older, and not the other way around like Benjamin Button - it's all because of entropy. So I think that entropy is underappreciated as something that has a crucial role in how we go through life.

The speed of time is 1 hour per hour, no matter what else is going on in the universe.

God is not described in equations.
